An Internet of things (IoT) wireless communication module. The IoT wireless communication module comprises an antenna, a radio transceiver coupled to the antenna, an embedded universal integrated circuit card (eUICC) coupled to the radio transceiver, where the eUICC is provisioned with a plurality of eSIM profiles, a non-transitory memory, a processor coupled to the non-transitory memory, to the radio transceiver, and to the eUICC, and an eSIM profile adapter application stored in the non-transitory memory. When executed by the processor, the eSIM profile adapter application determines a system installation context of the IoT wireless communication module, selects one of the plurality of eSIM profiles stored in the eUICC based on the system installation context, and activates the selected eSIM profile in the eUICC.

A subscriber identity module (eUICC), comprises profiles for the utilization of a mobile terminal that include at least a first profile and at least a second profile, of which the second profile (Pr1, Pr2) is devised as an active profile. The first profile is designed as a root profile (PrR) which in a normal state of the subscriber identity module is in an inactive state, and which is devised to be activated in response to an authentication command (AUTHENTICATE) received at the subscriber identity module. The authentication command is specially parameterized for the root profile (PrR) with a specific root value of the network parameter (P2) to be activated during a change-over period. The initially active second profile (Pr1, Pr2) is deactivated during the change-over period. After the end of the change-over period, the first profile (PrR) is again deactivated and the second profile (Pr1, Pr2) is again activated.

An apparatus for wireless communication is provided. The apparatus is configured to obtain, based on a first mobile alert associated with a first subscriber identity module (SIM) being scheduled for broadcast from a first network, an indication of receiver resources assigned for receiving the first mobile alert associated with the first SIM. The apparatus is further configured to refrain, based at least in part on the indication, from receiving a second mobile alert associated with a second SIM scheduled for broadcast from a second network. The first mobile alert and the second mobile alert may be associated with messages from at least one of a CMAS or an ETWS.

A method for remotely performing secure change of operational mode of a telecommunications device, the method comprising: establishing a first secure channel between a modem of the telecommunications device and an application executing in an Execution Environment of the telecommunications device; establishing a second secure channel between the application and a remote server; enabling the modem in a limited operational mode; generating a request, by the modem or the application, to verify the validity of a subscriber identity module of the telecommunications device; retrieving, by the modem, module identification information from the subscriber identity module; retrieving verification information, by the application and from the remote server, using the second secure channel, sending the module identification information from the modem to the application using the first secure channel, verifying at the application whether the subscriber identity module is valid using the module identification information and the verification information, and sending the verification result from the application to the modem using the first secure channel, or retrieving verification information, by the application and from the remote server, using the second secure channel, sending the verification information from the application to the modem using the first secure channel and verifying at the modem whether the subscriber identity module is valid using the module identification information and the verification information, or sending the module identification information from the modem to the remote server, verifying at the remote server whether the subscriber identity module is valid using the module identification information and verification information available at the server, sending the verification result from the remote server to the application using the second secure channel, and sending the verification result from the application to the modem using the first secure channel; responsive to a positive verification of the subscriber identity module transitioning the modem from the limited operational mode to an enhanced operational mode.

The disclosure relates to communication techniques for merging 5th generation (5G) communication systems with internet-of-things (IoT) technology to support a high data transmission rate in post-4th generation (4G) system and systems therefor.
